Portable Conductivity/Dissolved Oxygen Meter




  • بررسی و خرید
  • Description :

    Multiparameter portable Conductivity/Dissolved Oxygen meter contains 5 measurement modes. The meter is suitable for measuring the Conductivity, TDS, Salinity, Resistivity and DO of the liquids.

    Conductivity/TDS/Salinity/Resistivity Mode:

    • Multiparameter portable Conductivity/Dissolved Oxygen meter is equipped with a large backlit LCD display.

    • 1 to 5 points push-button calibration with automatic calibration solution recognition.
    • Selectable cell constant (0.1/1/10), normalization temperature (20/25°C), TDS conversion factor, seawater and practical salinity measurement modes.

    • Linear or pure water compensation improves measurement accuracy of meter.

    Dissolved Oxygen Mode:

    • 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
    •Manual salinity and barometric pressure compensation improve the measurement accuracy.
    Other Features:

    • Automatic Temperature Compensation provides accurate reading over the entire range.

    • Calibration Due Reminder prompts user to calibrate the meter regularly.
    • Stability indicator automatically shows current measurement status.

    • Auto-Hold function freezes stable measured value for easy viewing and recording.
    • Manual temperature calibration corrects temperature deviation.

    • Selectable temperature unit (°C or °F) meets different application requirements.

    • Help message as a operational guide that helps you quickly begin using the meter.
    • System menu allows setting the 13 parameters, including the number of calibration points, resolution, stability condition, measurement unit, etc.

    • Reset feature automatically resumes all parameters back to factory default settings.

    • Expanded memory stores and recalls up to 500 readings.

    • Built-in real-time clock stamps stored data to meet GLP standard.

    • Stored data can be transferred into computer by USB communication interface.

    • Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use the meter smoothly.
